Hi everyone, I don’t understand how we ended up with (1-1/365)^(n^2) as a final solution. The question itself is ambiguous: Is it 2 rooms each with n students? Or is it 2 rooms with a total of n students? If it is the latter, then how is n divided up in the 2 rooms? Assuming we have n students…

Wk 1 Birthday problem 4 might have wrong algebra at the minimum (the logic might be flawed as well)

Now, I see your pov.

However, there is a fatal issue. You are using addition rule instead of multiplication rule. Subtracting the result of addition rule from 1, however, won’t obtain P_4.
